If we see the picture that explains the making of glass, we can say it looks like easy to make a glass. The picture, of course, is simplified. The real proccess maybe more complicated than we see in the picture, but I'm going to highlighted the main proccess of making a glass. First, raw materials like sand, soda, and limestone are put in a furnace. The ingredient then divided into two ways, one for make a plate glass and the other for make a bottle glass. The ingredient for make a plate glass is placed in a large tray. Next, it's moved to a rollers which make the ingredient become a plate glass. The same thing is occured in the way to make a bottle glass. Instead of rollers, a removable mould is used to shape the glass into bottle. Air also contribute by get through on the removable mould. Finally, the proccess creates two types of glass. Now we know how to make a glass in a simply explanation.
